\multicolumn{4}{p{14.1cm}}{\textit{Notes}:  This table displays average characteristics by NSR grandfathering status.  Standard deviations are in parentheses, with \textit{t}-statistics of the difference between `grandfathered' and `non-grandfathered' boilers in brackets where *** p<0.001;  ** p<0.01;  * p<0.05.  All variables utilize boilers with inservice years between 1950 and 2004 inclusive, except for those from CEMS which are from 1997 onwards and are identified with a $^{\dagger}$. Each row is a separate calculation, and is not conditional on the other variables reported here.} \\
